is a bacterium that is commonly associated with food-borne infections and is regarded as one of the most important pathogens in public health. serovars, particularly Typhimurium and Enteritidis, which are widely distributed globally, mainly result in outbreaks commonly linked to the consumption of animal products. This study is a systematic review and meta-analysis of studies reporting the prevalence of serovars from one health perspective that included human, environmental, and animal samples in South Africa. PubMed, ScienceDirect, African Journals Online, and Scopus databases were used to conduct extensive searches of articles which were ultimately included or excluded following the Systematic Reviews and Meta-Analysis (PRISMA) guidelines. According to the data obtained in this review, the overall pooled prevalence estimates (PPE) of serovars detection were 79.6%, 61.6%, 56.5%, and 43.2% for human, environment, animal, and environment/animal samples in South Africa, respectively. The majority of the studies (50%) used the polymerase chain reaction (PCR) technique for the detection of serovars, followed by culture methods (26.7%), while 20% used serotyping. The PPE for nontyphoidal (NTS) was 65.6% and 34.4% for Typhimurium and Enteritidis, respectively. Our data further shows that 3 serovars, namely, Typhimurium, Enteriditis, and Hadar, have been isolated from animals, humans, and the environment in South Africa. Our results highlight the ongoing spread of spp. especially on animals which might end up infecting humans via direct contact with infected animals or eating infected animal products. This calls for deliberate "One Health" epidemiological studies in order to document information on the transmission between humans, animals, and the environment. This will ultimately result in the formulation of a consolidated salmonellosis control policy by the environmental, human, and veterinary health sectors.
是一种通常与食源性感染相关的细菌，被视为公共卫生领域最重要的病原体之一。血清型，特别是鼠伤寒血清型和肠炎血清型，在全球广泛分布，主要导致通常与食用动物产品有关的疫情爆发。本研究是一项系统综述和荟萃分析，从“同一个健康”的角度对南非人类、环境和动物样本中血清型的流行情况进行研究。使用PubMed、ScienceDirect、非洲期刊在线数据库和Scopus数据库对文章进行广泛检索，最终根据系统综述和荟萃分析（PRISMA）指南纳入或排除文章。根据本次综述获得的数据，南非人类、环境、动物以及环境/动物样本中血清型检测的总体合并患病率估计值分别为79.6%、61.6%、56.5%和43.2%。大多数研究（50%）使用聚合酶链反应（PCR）技术检测血清型，其次是培养方法（26.7%），而20%使用血清分型。非伤寒沙门氏菌（NTS）的合并患病率估计值中，鼠伤寒血清型为65.6%，肠炎血清型为34.4%。我们的数据进一步表明，在南非，已从动物、人类和环境中分离出3种血清型，即鼠伤寒血清型、肠炎血清型和哈达尔血清型。我们的结果突出了沙门氏菌的持续传播，尤其是在动物身上，这可能最终通过直接接触受感染动物或食用受感染动物产品而感染人类。这就需要开展审慎的“同一个健康”流行病学研究，以记录人类、动物和环境之间传播的信息。这最终将促使环境、人类和兽医卫生部门制定统一的沙门氏菌病控制政策。
